FEATURES AND FUNCTIONS

INVERTERAt the start of operation, a large power is used to bring the room quickly to the desired temperature. Afterwards, the unit automatically switches to a low power setting for economic and comfortable operation.

COIL DRY OPERATIONThe Indoor unit can be dried by pressing the COIL DRY button on the Remote Controller so as to avoid going moldy and restrain the breed of bacterium.

AUTO CHANGEOVERThe operation mode (cooling, dry, heating) is switched automati-cally to maintain the set temperature, and the temperature is kept constant at all times.

PROGRAM TIMERThe program timer allows you to integrate OFF timer and ON timer operations in a single sequence. The sequence can involve one transition from OFF timer to ON timer, or from ON timer to OFF timer, within a twenty-four hour period.

SLEEP TIMERWhen the SLEEP button is pressed during Heating mode, the air conditioner’s thermostat setting is gradually lowered during the period of operation; during cooling mode, the thermostat setting is gradually raised during the period of operation. When the set time is reached, the unit automatically turns off.

WIRELESS REMOTE CONTROLLERThe Wireless Remote Controller allows convenient control of air conditioner operation.

HORIZONTAL AIRFLOW: COOLING/DOWNWARD AIRFLOW: HEATING

For cooling, use horizontal airfl ow so the cool air does not blow directly on the occupants in the room. For heating, use down-ward airfl ow to send powerful, warm air to the fl oor and create a comfortable environment.

OMNI-DIRECTIONAL AIR FLOW(SWING OPERATION)

Three-dimensional control over air direction swing is possible through dual use of both an UP/DOWN air direction swing and RIGHT/LEFT air direction swing. Since UP/DOWN air direction fl aps operate automatically according to the operating mode of the unit, it is possible to set air direction based on the operating mode.

REMOVABLE OPEN PANELThe indoor unit’s Open Panel can be removed for easy cleaning and maintenance.

MILDEW-RESISTANT FILTERThe AIR FILTER has been treated to resist mildew growth, thus allowing cleaner use and easier care.

SUPER QUIET OPERATIONWhen the FAN CONTROL button is used to select QUIET, the unit begins super-quiet operation; the indoor unit’s airfl ow is reduced to produce quieter operation.

POLYPHENOL CATECHIN AIR CLEANING FILTERThe polyphenol catechin air cleaning fi lter uses static electricity to clean the air of fi ne particles and dust such as tobacco smoke and plant pollen that are too small to see.The fi lter contains catechin, which is highly effective against various bacteria by suppressing the growth of the bacteria ad-sorbed by the fi lter.Note that when the air cleaning fi lter is installed, the amount of air produced decreases, causing a slight decrease in the air conditioner’s performance.

NEGATIVE AIR IONS DEODORIZING FILTERIt comprises pottery super micro particles, which can produce negative air ions having the effect of deodorizing and can absorb and remit the peculiar smell at home.

The optional wired remote controller (model No. : UTB-YUD) can be used.When you use remote controller, there are following different points as compared with using wireless remote controller.[The additional functions for wired remote controller]● Weekly timer ● Temperature set back timer[The restricted functions for wired remote controller]● ECONOMY ● MAINTENANCE ● THERMO SENSORAnd you can't use both wired remote controller and wireless remote controller simultaneously.(Only one kind can be selected)

WARNING!

Before requesting service, perform the following checks:

Symptom Problem See Page

NORMAL FUNCTION

Doesn’t operate immedi-ately:

● If the unit is stopped and then immediately started again, the com-pressor will not operate for about 3 minutes, in order to prevent fuse blowouts.

● Whenever the Power Supply Plug is disconnected and then reconnected to a power outlet, the protection circuit will operate for about 3 minutes, preventing unit operation during that period.

—

Noise is heard: ● During operation and immediately after stopping the unit, the sound of water fl owing in the air conditioner’s piping may be heard. Also, noise may be particularly noticeable for about 2 to 3 minutes after starting operation (sound of coolant fl owing).

● During operation, a slight squeaking sound may be heard. This is the result of minute expansion and contraction of the front cover due to temperature changes.

—

● During Heating operation, a sizzling sound may be heard occasional. This sound is produced by the Automatic Defrosting operation. 15

Smells: ● Some smell may be emitted from the indoor unit. This smell is the result of room smells (furniture, tobacco, etc.) which have been taken into the air conditioner.

—

Mist or steam are emitted: ● During Cooling or Dry operation, a thin mist may be seen emitted from the indoor unit. This results from the sudden Cooling of room air by the air emitted from the air conditioner, resulting in condensation and misting.

—

● During Heating operation, the outdoor unit’s fan may stop, and steam may be seen rising from the unit. This is due to Automatic Defrosting operation.

be washed and reused.)● For storage of the Air Cleaning Filters, use the fi lters as soon

as possible after the package has been opened. (The air cleaning effect decreases when the fi lters are left in

the opened package)● Generally, the fi lters should be exchanged about every three

months.Please buy delicated air cleaning fi lters (UTR-FA13-1) (Sold separately) to exchange the used dirty air cleaning fi lters.

[Negative air ions deodorizing fi lter (one sheet) — light blue]● The fi lters should be exchanged about every three years so

as to maintain the deodorizing effect.● Filter frame is not a one-off product.

Please buy delicated deodorizing fi lter (UTR-FA13-2) (Sold separately) when exchanging the fi lters.

Maintenance of Deodorizing FiltersIn order to maintain the deodorizing effect, please clean the fi lter in the follow way once three months.1 Remove the deodorizing fi lter.2 Clean with water and dry in the air.

1) Flush the fi lters with high-pressure hot water until the surface of the fi lters are covered with water. Please fl ush with diluent neutral detergent.

Microcomputer-controlled Automatic Defrosting● When using the Heating mode under conditions of low outdoor

temperature and high humidity, frost may form on the outdoor unit, resulting in reduced operating performance.

In order to prevent this kind of reduced performance, this unit is equipped with a Microcomputer-controlled Automatic Defrost-ing function. If frost forms, the air conditioner will temporarily stop, and the defrosting circuit will operate briefl y (for about 7-15 minutes).

During Automatic Defrosting operation, the OPERATION Indicator Lamp (red) will fl ash.

Operation and Performance

Heating Performance● This air conditioner operates on the heat-pump principle,

absorbing heat from outdoor air and transferring that heat indoors. As a result, the operating performance is reduced as outdoor air temperature drops. If you feel that insuffi cient heating performance is being produced, we recommend you use this air conditioner in conjunction with another kind of heating appliance.

● Heat-pump air conditioners heat your entire room by recircu-lating air throughout the room, with the result that some time may be required after fi rst starting the air conditioner until the room is heated.

TROUBLESHOOTING

OPERATING TIPS

If the problem persists after performing these checks, or if you notice burning smells, or both the ORERATION Indicator Lamp (Fig. 3 5) and the TIMER Indicator Lamp (Fig. 3 6) fl ashes, or only the TIMER Indicator Lamp (Fig. 3 6) fl ashes, immediately stop operation, disconnect the Power Supply, and consult authorized service personnel.

Doesn’t operate at all: ● Is the Power Supply Plug disconnected its outlet?● Has there been a power failure?● Has a fuse blown out, or a circuit breaker been tripped?

—

● Is the timer operating? 8 - 9

Poor Cooling performance: ● Is the Air Filter dirty?● Air the air conditioner’s intake grille or outlet port blocked?● Did you adjust the room temperature settings (thermostat) correctly?● Is there a window or door open?● In the case of Cooling operation, is a window allowing bright sunlight

to enter? (Close the curtains.)● In the case of Cooling operation, are there heating apparatus and com-

puters inside the room, or are there too many people in the room?

—

● Is the unit set for SUPER QUIET operation? 6

The unit operates differently from the Remote Controller’s setting:

● Are the Remote Controller’s batteries dead?● Are the Remote Controller’s batteries loaded properly?
